[Pkg-rust-maintainers] Bug#1108775: rust-volatile: autopkgtest regression: `#![feature]` may not be used on the stable release channel

[Paul Gevers]

Source: rust-volatile
Version: 0.5.1-1
Severity: serious
User: debian-ci at lists.debian.org
Usertags: regression

Dear maintainer(s),

Your package has an autopkgtest, great. However, it fails since June 
2024. Can you please investigate the situation and fix it? I copied some 
of the output at the bottom of this report.

The release team has announced [1] that failing autopkgtest on amd64 and 
arm64 are considered RC in testing.

More information about this bug and the reason for filing it can be 
found on 
https://wiki.debian.org/ContinuousIntegration/RegressionEmailInformation

With my Release Team member hat on I allow you to tag this bug as 
trixie-ignore if this is nearly completely a test issue as it's so late 
in the freeze and it's not worth removing the package from trixie 
because of a failing test at this moment unless it exposes a much bigger 
issue. Having said that, if this is a test only issue and a fix is 
possible without fully removing the autopkgtest and without making the 
test superficial, it's still welcome, but it would need to happen soon.

Paul
